Abstract

A self-priming spackling compound includes between about 35% by weight and about 65% by weight acrylic latex resin, between about 20% by weight and about 50% by weight filler material, and between about 1% by weight and about 20% by weight water. In certain aspects, the latex resin may have an average latex particle size of less than about 0.18 microns, a minimum film formation temperature of less than about 15 degrees Celsius, and/or a glass transition temperature (Tg) of less than about 25 degrees Celsius. To further enhance the self-priming performance of the spackling compound, the formulation may further comprise a colorant such as titanium dioxide.

First claim

What is claimed is:

1. A spackling compound, comprising:
(a) between about 20% by weight and about 75% by weight acrylic latex resin;
(b) between about 15% by weight and about 65% by weight filler material; and
(c) between about 1% by weight and about 20% by weight water;
wherein the dried spackling compound passes the 6 mil hide test set forth in the specification.

2. The spackling compound of claim 1 , wherein the acrylic latex resin has a glass transition temperature (Tg) of less than about 25 degrees Celsius.

3. The spackling compound of claim 1 , further comprising at least one colorant.

4. The spackling compound of claim 3 , wherein the acrylic latex resin has a minimum film formation temperature of less than about 15 degrees Celsius.

5. The spackling compound of claim 3 , comprising between about 2% by weight and about 20% by weight colorant.

6. The spackling compound of claim 5 , wherein the colorant comprises titanium dioxide.

7. The spackling compound of claim 6 , wherein the colorant further comprises carbon black.

8. The spackling compound of claim 7 , wherein the carbon black comprises less than about 0.02 percent by weight of the spackling compound.

9. The spackling compound of claim 1 , further comprising a coalescing aid.

10. The spackling compound of claim 1 , wherein the coalescing aid comprises at least one of a sodium salt of polymeric carboxylic acid, an ester alcohol, glycol ethers, hydrocarbon molecules with an ether linkage, low molecular weight polyhydroxy molecules, or trimethylpentanediol monoisobutyrate.

11. The spackling compound of claim 1 , wherein the coalescing aid comprises less than about 1% by weight propylene glycol.

12. The spackling compound of claim 1 , further comprising a dispersing agent.

13. The spackling compound of claim 1 , wherein the dispersing agent comprises less than about 1 percent by weight of a sodium salt of polymeric carboxylic acid.

14. The spackling compound of claim 1 , further comprising a lubricant.

15. The spackling compound of claim 14 , wherein the lubricant comprises less than about 1% by weight hydroxy ethyl cellulose.

16. The spackling compound of claim 1 , wherein the filler comprises a bimodal distribution of particles.

17. The spackling compound of claim 16 , wherein the bimodal distribution of particles comprises at least one of glass bubbles and ceramic microspheres.

18. The spackling compound of claim 16 , wherein a particle size ratio of larger particle size filler to smaller particle size filler (as obtained by ratioing the median particle size of the two filler populations) is at least about 5:1.

19. The spackling compound of claim 1 , wherein the filler is substantially free of mined organic filler materials.

20. The spackling compound of claim 1 , wherein the dried spackling compound has an average 85 degree gloss retention index of at least about 0.3 when tested according to the method set forth in the present specification.
